The invention discloses a rudder blade supporting frame and a rudder blade mounting trolley. The rudder blade supporting frame comprises a fixing frame, two first drivers, two sets of first pulley assemblies, a first moving frame and a plurality of first flexible cables. The fixing frame is provided with a vertical channel with the top penetrating through, and the fixing ends of the two first drivers are fixed to the two sides of the fixing frame. The two first drivers are used for driving the two first pulley assemblies to move up and down. The first movable frame is located in the vertical channel and slidably connected to the fixed frame. The first flexible cable is wound above a pulley of the first pulley assembly, the two ends of the first flexible cable vertically extend downwards, one end of the first flexible cable is fixed to the fixing frame, and the other end of the first flexible cable is fixed to the first moving frame. By means of the first pulley assembly and the first flexible cable structure, the rudder blade supporting frame can adjust the height size of the rudder blade supporting frame according to the height size of a rudder blade needing to be supported. And the rudder blade mounting trolley can convey the rudder blade to a mounting position to finish mounting.
